Hi; I just bought an '89 Suburban and am trying to get it on the road. It has a tailgate, and the window doesn't operate properly. I found some mechanical problems: the tracks are a little ratty (I'll replace them), and the nylon wheels that run in the tracks are worn out (can they be replaced without replacing the whole assembly?). The window goes down with ease; I plugged in the power and put it down and it's still down! It wont't go up; doesn't even try. I assume the switch is supposed to just reverse polarity and the motor is supposed to run forwards or backwards. I tested the voltage at the plug which attaches to the motor; I get +5.8 volts when I put the switch in the down position; -0.38 volts in the up position; I was expecting -13V and +13V. I see a little switch at the right latch assembly; looks like something to do with not allowing one to operate the window with the gate open (or maybe not open the gate with the window closed???) In the morning, I'll disconnect the switch at the latch, and jump past it; then, next step, check the dash switch. Also, the keyed exterior switch is seized (maybe that's the problem??). Any suggestions? Thanks. Keith.
